Filter Cleaning Stations

PHARMINTECH Filter Cleaning Stations are engineered systems for safe, compliant cleaning of AHU pre‑filters, pocket filters, and housings used in cleanrooms and HVAC systems. 

Stations combine controlled washing, rinsing & drying with options for automated cycles, ultrasonic cleaning, while maintaining GMP compliance.

Product types and core functions

• Manual / Automated operation with high‑pressure spray and hot‑air drying for multiple pre‑filters per cycle.
• Loading booth with high‑pressure nozzles, detergent dosing, and integrated drying tunnel.

Key points

• Designed for washable and reusable filters only
• Provides repeatable, documented wash → rinse → dry cycles with PLC control and HMI recipe storage.
• Configurable capacity from single‑filter bench units up to multi‑rack systems to match site throughput.

Performance parameters

• Cycle capacity: 1–20 filters per cycle (model dependent).
• Typical cycle time: 20–90 minutes (wash → rinse → dry).
• Wash pressure: Pre‑wash 1–5 bar; main wash adjustable 30–120 bar.
• Ultrasonic option: 25–40 kHz tanks (optional).
• Drying: HEPA‑filtered warm air; ambient to 80°C; RH control optional.
• Final blow‑off: HEPA‑filtered compressed air for inspection.

Construction and materials

• Wetted parts: SS 316L standard; SS 304 optional.
• Internal finish: Smooth welds or 4B finish for easy cleaning.
• External panels: Powder-coated carbon steel, optional.
• Racks and baskets: Stainless steel, modular and removable.

Controls and instrumentation

• Control system: PLC with HMI touchscreen, recipe storage, and cycle logging.
• Alarms and indicators: Differential pressure, water level, temperature, leak detection, emergency stop.
• Validation ports: Sample ports for conductivity and visual inspection.
